Report  on  Commercial  Fertilizers,  1924.

THE  FERTILIZER  LAW. 

The  provisions  of  the  fertiHzer  law  have  been  discussed  in 
previous  reports  but  for  more  ready  reference  the  essential  features 
may  be  repeated. 

Significance  of  the  Term  "Commercial  Fertilizers" 

Explaining  what  is  meant  by  the  term  "commercial  fertilizers" 
the  law  says ; 

"The  term  'commercial  fertilizers'  shall  be  construed  to  mean  any  and 
every  substance  imported,  manufactured,  prepared  or  sold  for  fertilizing  or 
manuring  or  soil  amendment  purposes,  except  barnyard  manure  and  stable 
manure  which  have  not  been  artificially  treated  or  manipulated,  marl  and 
lime.  Cottonseed  meal,  rapeseed  meal,  castor  pomace  and  all  other  vege- 
table products  used  as  fertilizers,  including  the  ashes  of  cotton  hulls  and 
wood  ashes,  shall  be  included  as  fertilizers  within  the  meaning  of  this  act 
and  separate  analysis  fees  shall  be  paid  on  each  different  grade  which  is 
sold  or  offered  for  sale  in  the  state.  The  person  responsible  for  paying  the 
fees  above  prescribed  may  deduct  from  the  total  tonnage  sold  such  sales  of 
cottonseed  meal  or  other  vegetable  products  as  are  made  to  anyone  who 
gives  a  written  certificate  on  a  form  supplied  by  the  Connecticut  Agricul- 
tural Experiment  Station  stating  that  the  material  bought  by  him  was  to 
be  used  exclusively  for  feed  and  not  for  fertilizer." 

Concerning  Cottonseed  Meal. 

Cottonseed  meal  is  a  fertilizer  within  the  meaning  of  the  Statute 
but  it  is  provided  that  when  this  product  is  sold  for  feeding  purposes 
only,  it  shall  be  exempt  from  the  tonnage  tax. 

The  status  of  cottonseed  meal  under  the  fertilizer  law  has  been 
clearly  stated  in  'a  bulletin^  from  this  Station  from  which  the 
following  may  be  quoted : 

Registration  and  analysis  fees.  "Each  brand  of  cottonseed  meal  must  be 
registered  on  forms  provided  by  this  Station  and  an  analysis  fee  of  ten 
dollars  paid  on  it  before  it  is  sold,  offered  or  exposed  for  sale,  and  on  the 
first  day  of  January  annually  thereafter. 

"A  distinctive  name  constitutes  a  distinct  brand.  If  shipments  have 
different  guaranties  of  composition  they  are  held  to  be  different  brands." 

Branding  or  tagging.  "Since  nitrogen  is  the  only  fertilizer  ingredient  con- 
sidered in  the  trade  in  cottonseed  meal  no  guaranty  of  phosphoric  acid  or 
potash  is  required.  If  either  is  guaranteed  by  the  manufacturer,  however, 
an  additional  fee  of  ten  dollars  must  be  paid  on  each  element.  The  state- 
ment of  composition  now  legal  for  feeds  may  be  used  hereafter  if  the  per- 
centage of  nitrogen  is  stated. 

1  Bull,  of  Information  No.  9,  1919. 


4  CONNECTICUT    EXPERIMENT    STATION  BULLETIN   261. 

"Note  that  the  law  regarding  feeding  stufifs  forbids  the  use  of  metal  in 
attaching  tags  and  requires  that  each  package  shall  be  branded  or  tagged 
with  the  statement  required  by  law." 

Duties  of  shippers.     "It  is  assumed  from  correspondence  with  shippers 
outside  the  state  that  they  will  register  the  brands  which  they  sell  in 
Connecticut,  will  pay  analysis  fees  as  has  been  done  in  the  past  by  manu- 
facturers of  commercial  fertilizers,  and  will  semi-annually  thereafter  pay 
the  tonnage  fees. 

"They  will  report  to  this  Station  their  total  sales  and,  if  they  wish,  may 
report  what  part  has  been  sold  for  feed  exclusively.  From  the  reports  of 
dealers  within  the  state  it  will  be  possible  to  determine  quite  closely  the 
amounts  of  each  brand  actually  used  as  feed. 

"In  the  case  the  jobber  outside  the  state  neglects  or  refuses  to  register  a 
brand,  the  dealer  who  sells  it  within  the  state  is  responsible  under  the  law." 

Duties  of  dealers.  "Dealers  are  required  to  file  with  the  director  of  the 
Station  on  July  first  of  each  year  and  semi-annually  thereafter  a  sworn 
s.tatement  of  their  total  sales  of  each  brand  of  cottonseed  meal  and  the 
amount  of  each  sold  exclusively  for  feed,  during  the  preceding  six  months." 

Requirements  to  be  Complied  with  by  Sellers  of  Commer- 
cial Fertilizers. 

The  seller  is  responsible  for  the  proper  labeling  of  each  pack- 
age, for  the  registration  at  the  Station  of  every  brand  sold  by  him 
and  for  the  payment  of  the  analysis  fee,  before  offering  for  sale, 
and  annually  thereafter  on  January  1st. 

The  law,  specifies  the  information  which  shall  be  given  on  the 
label  as  follows: 

1.  Weight  of  each  package  in  pounds. 

2.  Brand  name  or  trade  mark. 

3.  Analysis: 

(a)  Available  phosphoric  acid,  per  cent. 

(b)  Total  phosphoric  acid,  per  cent. 

(c)  Nitrogen,  per  cent. 

(d)  Equivalent  ammonia,  per  cent. 

(e)  Potash  soluble  in  water,  per  cent. 

4.  Name  and  address  of  the  manufacturer  or  of  the  person  who  is 
responsible  for  the  statements  of  the  guaranty. 

In  the  case  of  bone  meal,  tankage  or  other  organic  products,  and 
in  basic  slag  and  mineral  phosphates  in  which  a  large  percentage  of 
the  phosphoric  acid  is  not  available  by  laboratory  methods,  the 
phosphoric  acid  shall  be  claimed  as  total  phosphoric  acid  unless 
it  is  desired  to  claim  available  phosphoric  acid  instead,  in  which 
case  the  guaranty  shall  take  the  form  set  forth  above. 

The  label  may  be  a  tag  attached  to  the  package  or  a  statement 
printed  thereon.  Percentages  shall  be  minimum  percentages 
only. 

The  presence  of  leather  in  its  various  forms,  wool  waste,  hair 
or  any  inert  nitrogenous  material  shall  be  declared  on  the  label 
unless,  by  processing,  the  activity  of  these  materials  has  been 
rendered  satisfactory  as  determined  by  official  methods. 


THE    FERTILIZER   LAW  O 

When  potash  is  derived  from  sulphate  or  carbonate  of  potash 
it  may  be  so  claimed, 

No  claim  or  guaranty  for  less  than  0.82  per  cent  of  nitrogen,  or 
for  less  than  1  per  cent  of  phosphoric  acid,  or  for  less  than  1  per  cent 
of  potash  shall  be  regarded  in  the  registration  or  analysis  of  any 
commercial  fertilizer. 

The  seller  must  also,  on  the  1st  of  January  and  July,  report 
the  tonnage  of  fertilizer  sold  within  the  preceding  six  months  and 
pay  to  the  director  of  the  Station  a  tonnage  fee  of  6  cents  per  ton. 

On  request,  copies  of  the  law  and  blanks  for  registration  and  for 
tonnage  reports  will  be  supplied  by  the  Station. 

If,  however,  proper  labeling,  registration  and  payments  have 
been  provided  for  by  the  manufacturer  of  the  brands  or  by  another 
responsible  person,  all  sellers  of  such  brands  are  released  from  the 
above  mentioned  requirements.  The  retailer,  therefore,  should 
assure  himself  that  the  requirements  of  the  laiv  have  been  met  by  the 
manufacturers  of  the  brands  which  he  handles,  or  himself  be  prepared 
to  meet  all  these  requirements. 

Precautions  to  be  Observed  in  Drawing  Samples  for 

Analysis. 

The  analysis  of  a  fertilizer  is  of  no  A^alue  unless  the  sample 
analyzed  represents  as  nearly  as  possible  the  stock  from  which  the 
sample  was  drawn.  The  law  prescribes  the  procedure  to  be  follow- 
ed by  authorized  agents  of  this  Station  when  taking  official  samples 
for  analysis  as  follows : 

"When  samples  are  taken  from  fertilizers  in  bags,  a  tube  shall  be  used, 
and  it  shall  be  inserted  at  one  end  of  the  bag  and  shall  pass  substantially 
the  entire  length  of  the  bag,  so  as  to  take  a  core  of  the  material  being 
sampled  from  substantially  the  entire  length  of  the  bag.  Samples  thus 
taken  from  individual  bags  shall  be  thoroughly  mixed,  and  the  official 
samples  shall  be  taken  from  the  mixture  so  drawn  by  the  method  known 
as  'quartering'.  Samples  of  fertilizer  taken  as  herein  provided  shall  be 
taken  from  at  least  five  per  centum  of  the  separate  original  unopened 
packages  in  the  lot,  for  the  mixture  from  which  the  official  samples  shall 
be  taken.  If  less  than  one  hundred  bags  are  in  the  lot,  at  least  five  bags 
shall  be  sampled;  if  less  than  five  bags,  all  shall  be  sampled.  Broken 
packages  shall  not  be  sampled." 

Gratuitous  Analyses. 

Under  the  fertilizer  law  the  Station  is  charged  only  with  the 
analysis  of  samples  drawn  by  its  own  agents.  It  does,  however, 
each  year  analyze  a  considerable  number  of  samples  drawn  by 
individuals,  representing  stock  purchased  by  them  for  their  own 
use.  The  object  of  the  purchaser  is  to  satisfy  himself  as  to  whether 
he  has  obtained  goods  of  the  grade  represented  and,  perhaps,  to 
obtain  evidence  upon  which  to  base  a  claim  for  shortage  should  the 
materials  not  meet  their  guaranties.  The  Station  assumes  no 
responsibility  for  the  sampling  in  case  of  such  unofficial  samples 


6  CONNECTICUT   EXPERIMENT   STATION  BULLETIN   261. 

and  can  only  vouch  for  the  accuracy  of  the  results  obtained  on  the 
materials  as  submitted.  Since  a  representative  sample  is  as 
essential  as  an  accurate  analysis  in  judging  the  quality  of  a  ship- 
ment of  fertilizer,  it  is  evident  that  a  satisfactory  adjustment  will 
seldom  be  effected  on  the  basis  of  an  unofficial  sample.  Notwith- 
standing certain  objections  which  may  be  raised  to  the  practice 
of  analyzing  samples  submitted  by  individuals,  the  Station  is 
disposed  to  continue  such  work  so  long  as  there  is  evidence  that  it 
constitutes  a  useful  service;  it  cannot,  however,  undertake  for  any 
one  individual  or  group,  work  in  such  volume  or  with  such  fre- 
quency that  it  becomes  a  systematic  control  over  current  purchases. 
This  clearly  invades  the  field  of  the  commercial  laboratory.

INSPECTION  OF  1924. 

During  the  year,  Mr.  Churchill,  the  sampling  agent  of  the 
Station,  has  visited  ninety-six  towns  and  villages  in  the  State  and 
has  taken  592  official  samples  of  fertilizers  which  number  includes 
all  the  registered  brands  which  were  found  on  sale.  These  together 
with  samples  submitted  by  purchasers  or  others  interested  may  be 
classified  as  follows:

I.     RAW  MATERIALS  CHIEFLY  VALUABLE  FOR 
NITROGEN. 

NITRATE  OF  SODA. 

Pure  nitrate  of  soda  contains  16.47  per  cent  of  nitrogen.  Com- 
mercial grades  of  this  salt  generally  contain  from  15  to  16  per  cent 
of  nitrogen  which  is  equivalent  to  from  18.2  to  19.5  ammonia  or 
91  to  97  per  cent  nitrate  of  soda. 

Twenty-three  samples  were  examined  and  the  results  are  given 
in  Table  I. 

Sample  23039  was  considerably  under  guaranty  and  a  second 
sample,  23306,  from  the  same  lot  was  also  deficient.  Sample 
23013  was  found  to  be  deficient  but  a  second  sample  of  the  same 
brand  taken  from  a  different  source  was  well  over  the  guaranty. 
Two  samples,  Nos.  23204  and  23205,  submitted  by  purchasers, 
were  found  to  be  considerably  under  the  guaranty  of  15  per  cent 
nitrogen.  The  salt  was  red-brown  in  color  and  contained  much 
insoluble  matter.  The  Apothecaries  Hall  Company,  who  distrib- 
uted this  chemical,  sold  in  original  bags  as  received  by  them.  They 
investigated  and  found  that  the  low  grade  product  constituted  but 
a  small  part  of  their  entire  stock;  they  were  allowed  a  rebate  by  the 
importers  from  whom  they  bought  and  reimbursed  their  customers 
accordingly. 

Nitrogen  from  this  source  has  cost  from  20.6  to  28.9  cents  per 
pound,  the  average  being  about  23.3  cents.  Ton  prices  have  ranged 
from  $62.50  to  $76.00. 

We  are  uncertain  about  the  guaranties  on  samples  21899, 21900, 
21901  and  21902.  The  jobbers  claim  the  goods  were  guaranteed 
15  per  cent  nitrogen,  while  the  information  submitted  by  the 
purchasers  is  that  the  salt  was  supposed  to  analyze  95  per  cent 
nitrate  of  soda,  which  is  about  15.60  per  cent  nitrogen.  We  have 
no  information  as  to  whether  any  adjustment  was  made  or  asked 
for.

SULPHATE  OF  AMMONIA. 

Ten  samples  were  examined  and  the  results  are  given  in  Table  IL 

Pure  ammonium  sulphate  contains  21.2  per  cent  of  nitrogen,  but 
the  commercial  grades  usually  contain  about  20.5  per  cent,  which 
is  equivalent  to  about  25  per  cent  of  ammonia  or  about  97  per  cent 
of  ammonium  sulphate. 

As  sold  in  the  State  this  year  this  salt  has  contained  from  20.2 
to  20.9  per  cent  of  nitrogen.  Sample  23240  was  a  second  sample- 
drawn  as  a  check  on  sample  23146;  both  were  substantially  up  to 
the  guaranty.  Sample  161  was  a  check  on  23011  and  exceeded 
the  guaranty,  whereas  the  first  sample  was  slightly  low.  Sample-- 
23395  showed  a  shortage  of  0.33  per  cent  nitrogen.  This  was  a. 
small  lot  and  was  not  resampled. 

According  to  prices  quoted,  the  cost  per  pound  of  nitrogen  has- 
ranged  from  9.8  to  19.3  cents,  the  average  being  16.6  cents;  this  i^ 
$3.32  per  unit  of  nitrogen,  or  $2.73  per  unit  of  ammonia.  Ton- 
prices  have  ranged  from  $40.00  to  $79.00.

CASTOR   POMACE  21 


CASTOR  POMACE. 


Castor  pomace  is  the  residue  left  after  removing  the  oil  from  the 
castor  bean.  It  is  actively  poisonous  to  stock  and  should  be  stored 
with  due  precautions  on  that  account.  As  a  fertilizer  it  is  used 
chiefly  with  cottonseed  meal  in  tobacco  mixtures.  While  valuable 
chiefly  for  its  nitrogen  content  it  contains  also  about  one  per  cent 
of  potash  and  two  per  cent  of  phosphoric  acid. 

Fifty-eight  samples  were  analyzed  and  the  results  are  given 
in  Table  III.  Fifteen  were  sampled  by  the  station  agent;  the 
remainder  were  sampled  and  submitted  by  purchasers. 

Sample  22813  was  submitted  by  the  purchaser  and  was  drawn 
from  three  bags.  The  stock  was  left  over  from  the  previous  year 
but  when  bought  was  guaranteed  to  contain  5  per  cent  of  nitrogen. 
Sample  22951  was  sampled  by  the  station  agent  from  six  bags 
of  the  lot,  and  samples  22953  and  22960  were  taken  from  each  of 
two  bags  which  were  represented  in  the  original  purchaser's  sample. 
The  two  single  bag  samples  show  a  variation  in  nitrogen  of  about 
1  per  cent.  The  entire  purchase  of  the  previous  year  cannot  be 
adequately  judged,  however,  by  these  samples  from  the  left-over 
stock. 

In  general,  this  material  has  been  sold  this  year  under  a  guaranty 
of  4.52  per  cent  nitrogen,  which  is  equivalent  to  5.50  per  cent  of 
ammonia.  In  fifty  samples  where  guaranties  are  known  there  were 
forty  in  which  the  guaranties  were  exceeded  and  ten  in  which  they 
were  not  met ;  but  for  the  total  number  there  was  an  average  over- 
run of  0.17  per  cent  of  nitrogen. 

At  the  prices  quoted  to  us,  confidentially  or  otherwise,  the 
average  cost  per  ton  is  $29.76.  The  average  nitrogen  content  is 
4.75  per  cent.  Disregarding  the  potash  and  phosphoric  acid  con- 
tents, nitrogen  has  cost  31.3  cents  per  pound,  which  is  $6.26  per 
unit  of  nitrogen  or  $5.13  per  unit  of  ammonia.  If  allowance  is 
made  for  the  potash  and  phosphoric  acid  present  at  the  rate  of  four 
cents  per  potmd  each,  then  the  cost  per  pound  of  nitrogen  is  about 
28.8  cents.

COTTONSEED  MEAL. 

One  hundred  and  thirty-five  samples  of  cottonseed  meal  have 
been  analyzed  and  the  results  are  given  in  Table  IV.  The  grades 
may  be  classified  as  follows : 

36  per  cent  protein  containing  5.76  per  cent  nitrogen  equivalent 
to  7.00  per  cent  ammonia,  16  samples. 

Jf-l  per  cent  protein  containing  6.56  per  cent  nitrogen  equivalent 
to  8.00  per  cent  ammonia,  82  samples. 

4-3  per  cent  protein  containing  6.88  per  cent  nitrogen  equivalent 
to  8.30  per  cent  ammonia,  17  samples. 

Four  samples  have  odd  guaranties  and  for  16  samples  no  guar- 
anties were  submitted.  There  were  no  samples  bearing  a  guaranty 
of  38.56  per  cent  protein  (6.17  per  cent  nitrogen  equivalent  to 
7.50  per  cent  ammonia). 

Of  these  samples  where  guaranties  are  known  82  equaled  or 
exceeded  their  guaranties  and  36  did  not.  As  an  average  for  all 
samples  there  was  0.15  per  cent  of  nitrogen  in  excess  of  the  guar- 
anty. 

Reckoning  nitrogen  at  its  average  cost  as  deduced  from  data 
obtained  this  year,  viz.,  39.1  cents  per  pound,  deficiencies  in  money 
value  in  excess  of  $1.00  per  ton  were  shown  in  only  15  samples. 
This  is  making  no  allowance  for  about  3  per  cent  of  phosphoric

25- 


acid  and  2  per  cent  of  potash  which  cottonseed  meal  normally  con- 
tains and  which  are  fairly  valued  at  4  cents  per  pound  each. 

So  far  as  we  have  information  as  to  prices,  the  cost  of  nitrogen  in- 
cottonseed  meal  has  averaged  39.1  cents  per  pound,  and  nitrogen  has- 
been  purchased  at  somewhat  better  advantage  in  the  higher  grades  as: 
appears  in  the  subjoined  summary.  Table  V.

Two  samples  purchased  by  Hatheway  &  Steane  from  Olds  8c 
Whipple  of  Hartford  were  submitted  by  the  purchasers.  Guar- 
anties were  not  given.  The  samples,  23174  and  23175,  contained 
5.77  and  5.96  per  cent  of  nitrogen  respectively,  equivalent  to  7.02 
and  7.25  per  cent  of  ammonia.  The  price  quoted  was  $Jf.5.50  per 
ton;  thus  nitrogen  cost  about  38.7  cents  per  pound.

ACID    PHOSPHATE  31 


II.      RAW   MATERIALS    CHIEFLY   VALUABLE   FOR 
PHOSPHORIC  ACID. 

RAW  ROCK  PHOSPHATE. 

Oiily  one  sample  was  analyzed. 

10.  Phos-Pho-Floiir.  Sold  by  W.  L.  Mitchell,  New  Haven, 
and  sampled  by  the  Station  agent  from  stock  of  H.  O.  Daniels, 
Middletown. 

It  was  guaranteed  to  contain  28  per  cent  of  total  phosphoric 
acid  and  30.95  per  cent  was  foiuid. 

PRECIPITATED  BONE  PHOSPHATE. 

The  bone  phosphate  of  commerce  is  obtained  as  a  by-product 
in  the  manufacture  of  gelatin  and  consists  largely  of  dicalcium 
phosphate.  The  phosphoric  acid  in  this  material  is  practically 
all  "available." 

Four  samples  were  analyzed,  all  of  which  exceeded  their  guar- 
anties. At  the  price  quoted,  available  phosphoric  acid  has  cost  6.3 
cents  per  pottnd.     The  ton  price  was  $50.00. 

Analyses  are  given  in  Table  VI. 

DISSOLVED  ROCK  PHOSPHATE  OR  ACID  PHOSPHATE. 

This  material  is  the  product  made  by  treating  raw  rock  phos- 
phate with  sulphuric  acid  whereby  the  phosphorus  is  largely 
converted  into  "available"  forms.  In  acid  phosphates  most  of 
the  available  phosphoric  acid  is  soluble  in  water. 

The  prevailing  guaranty  is  16  per  cent  of  "available"  phos- 
phoric acid,  and  this  amount  was  exceeded  in  all  of  the  twenty 
samples  examined. 

As  regards  "available"  phosphoric  acid  this  material  has  varied 
in  composition  within  the  limits  of  about  50  pounds  per  ton.  The 
price,  however,  has  ranged  from  $14.00  to  $30,00  and  the  cost 
per  pound  of  available  phosphoric  acid  has  accordingly  varied 
from  4.2  to  9.2  cents.  On  the  average,  acid  phosphate  this  year  has 
contained  16.73  per  cent  of  available  phosphoric  acid,  which  at  the 
average  price  {$21.11)  per  ton  has  made  the  cost  of  this  constituent 
6.3  cents  per  pound,  or  $1.26  per  unit. 

Analyses  are  given  in  Table  VII.

III.     RAW  MATERIALS  CONTAINING  POTASH. 

CARBONATE  OF  POTASH. 

Piire  carbonate  of  potash  contains  68.2  per  cent  of  actual 
potash  (K2O),  but  commercial  grades  usually  contain  from  60  to 
65  per  cent.  Most  of  the  samples  submitted  were  guaranteed  to 
contain  96  per  cent  carbonate  of  potash  which  is  equivalent  to 
65.44  per  cent  actual  potash. 

Thirteen  samples  were  analyzed,  all  but  one  being  submitted  by 
purchasers.  Two  samples,  Nos.  22494  and  22495,  failed  to  meet 
their  guaranties  by  3.01  and  2.18  per  cent  respectively;  these 
samples  were  from  the  same  stock  as  two  previous  samples  viz., 
22358  and  22356,  both  of  which  more  nearly  approached  the 
guaranty. 

Analyses  are  given  in  Table  VIII. 

MURIATE  OF  POTASH. 

The  usual  commercial  grade  of  this  salt  is  about  80  per  cent 
pure  containing  about  50.5  per  cent  actual  potash.  Because  it 
readily  absorbs  moisture,  guaranties  are  often  placed  somewhat 
lower,  viz.,  48  to  50  per  cent.  The  prevailing  guaranty  for  samples 
examined  this  year  was  50  per  cent. 

Thirteen  samples  were  analyzed,  four  of  which  contained  con- 
siderably less  than  48  per  cent.  Sample  22871  was  from  three 
bags  which  represented  the  remainder  of  a  four-ton  lot.  The 
analysis  may  not,  therefore,  be  representative  of  the  whole  ship- 
ment. 

Nos.  23140  and  23324  were  purchaser's  samples  from  the  same 
lot.  The  goods  were  sold  by  the  L.  T.  Frisbie  Company  and 
obtained  by  them  from  the  Consolidated  Rendering  Company  of 
Boston.  These  two  samples  were  considerably  below  the  guaranty 
of  50  per  cent;  an  official  sample,  23242,  taken  by  the  Station 
agent  at  the  plant  of  the  Frisbie  Company  exceeded  the  guaranty 
by  nearly  1.5  per  cent. 

The  average  for  all  samples  is  close  to  50  per  cent  {49.92),  of 
potash  which,  at  the  average  of  prices  quoted,  $4-4-4^>  makes  the  cost 
of  potash  in  this  material  4-5  cents  per  pound  or  90  cents  per  unit. 
The  lowest  cost  noted  is  3.8  cents,  and  the  highest  is  5  cents  per  pound. 

Analyses  are  given  in  Table  VIII. 

HIGH  GRADE  SULPHATE  OF  POTASH. 

The  commercial  grades  of  this  salt  generally  contain  about  48.0 
per  cent  of  potash  which  is  approximately  90  per  cent  sulphate  of 
potash. 

Twenty-six  samples  were  examined  of  which  ten  were  drawn 
by  the  Station  agent  and  the  remainder  by  purchasers.     The 


POTASH    SALTS  35 

official  samples  substantially  met  or  exceeded  their  guaranties. 
Several  samples,  submitted  by  purchasers,  while  of  fair  average 
quality  did  not  meet  the  guaranties  quoted  for  them  which  were 
over  50  per  cent.  Two,  22350  and  22535,  were  considerably  under 
48  per  cent. 

The  average  potash  content  was  49.1  per  cent  and  the  cost  per  pound, 
based  upon  the  few  prices  quoted,  averaged  5.5  cents. 

Seven  samples,  representing  early  season  purchases  of  the 
American  Simiatra  Tobacco  Co.,  were  submitted  by  the  purchasers. 
The  samples  purported  to  be  high  grade  sulphate  but,  on  analysis, 
only  one  conformed  to  that  grade,  the  others  containing  from  30 
to  40  per  cent  of  potash  with  considerable  and  varying  amoimts 
of  chlorine  and  magnesia.  Investigation  by  the  Station  agent 
showed  that  this  shipment  was  received  in  the  original  import 
sacks  distinguished  only  by  serial  numbers;  and  that  there  were 
two  grades  in  the  lot,  one  in  bags  marked  419  and  the  other  in  bags 
marked  482  and  600.  The  low  grade  stock  was  included  in  the 
shipment  by  mistake  and  replacement  was  made. 

Analyses  are  given  in  Table  VIII.

40  CONNECTICUT   EXPERIMENT    STATION  BULLETIN   261. 

DOUBLE  SULPHATE  OF  POTASH  AND  MAGNESIA 
OR  "DOUBLE  MANURE  SALTS". 

Six  samples  were  analyzed  this  year  and  the  results  are  given 
in  Table  IX. 

This  salt  contains  potash  and  magnesia  combined  as  sulphate 
and  is  relatively  free  from  chlorine,  which  makes  it  well  adapted 
for  use  in  tobacco  fertilizers.  It  generally  contains  from  25  to  28 
per  cent  of  potash  and  from  8  to  12  per  cent  of  magnesia.  In  the 
last  three  years,  however,  seven  out  of  twenty-one  samples  exam- 
ined by  us  have  shown  amounts  of  magnesia  less  than  8  per  cent, 
these  ranging  from  6.6  down  to  as  low  as  3  per  cent.  In  only  four 
of  the  total  number  has  chlorine  exceeded  4  per  cent  and  in  none 
has  it  reached  5  per  cent. 

The  average  potash  content  in  samples  analyzed  this  year  is  27.67 
per  cent  and  the  average  cost  per  pound  of  potash,  at  the  prices  quoted, 
is  5.1  cents.

IV.  RAW  MATERIALS  CONTAINING  NITROGEN  AND 

POTASH. 

One  sample  of  nitrate  of  potash  and  three  of  nitrate  of  soda 
and  potash  have  been  analyzed,  all  sampled  by  the  Station  agent. 

23020.  Nitrate  of  potash  from  Calcutta,  India.  Stock  of  the 
Lyman  Farm,  Middlefield. 

22924  Nitrate  of  Soda  and  Potash.  Sold  by  Apothecaries  Hall, 
sampled  from  stock  of  J.  A.  Glasnapp,  West  Cheshire. 

23416.  Nitrapo.  Sold  by  Nitrate  Agencies  Co.,  sampled  from 
stock  of  F.  H.  Thrall,  Windsor. 

191.  Nitrapo.  Sold  by  Nitrate  Agencies  Co.,  sampled  from 
stock  of  E.  N.  Austin,  Suffield. 

Analyses  are  given  in  Table  X. 

Table  X,     Analyses  of  Nitrate  of  Potash,  Etc. 

Station  No.  23020  22924  23416              191 

Nitrogen: 

found  12.60  15.46  14.30  11.78 

guaranteed  14.80  14.80  14.80 

Equivalent  ammonia: 

found  15.32  18.80  17.39  14.32 

guaranteed  18.00  18.00  18.00 

Potash: 

found  43.45  14.11  17.15  12.41 

guaranteed  12.00  15.00  15.00 

The  price  quoted  in  case  of  sample  22924  was  $75.00  per  ton. 
Allowing  5  cents  per  pound  for  potash  the  cost  of  nitrogen  was  19.6 
cents,  which  is  a  little  less  than  the  minimum  cost  calculated  for 
nitrate  of  soda  this  year. 

V.  RAW   MATERIALS   CONTAINING   NITROGEN   AND 

PHOSPHORIC  ACID. 
DRY  GROUND  FISH. 

Forty  samples  were  analyzed  and  the  results  are  given  in 
Table  XI. 

The  prevailing  guaranty  for  nitrogen  was  8.23  per  cent,  equiva- 
lent to  10  per  cent  of  ammonia.  The  guaranties  for  phosphoric 
acid  varied  from  4  to  9  per  cent. 

The  average  nitrogen  content  found  was  8.45  per  ce.nt,  equiva- 
lent to  10.27  per  cent  of  ammonia,  and  the  average  for  phosphoric 
acid  was  7.37  per  cent. 

Based  upon  the  average  cost  per  ton  as  quoted,  and  allowing 
5  cents  per  pound  for  phosphoric  acid,  nitrogen  in  this  material 
has  cost  about  37.9  cents  per  pound.  There  were  considerable 
overruns  in  phosphoric  acid  in  most  cases,  assuming  an  average 
where  no  guaranty  was  given.  Taking  these  into  account,  there 
were  no  deficiencies  in  nitrogen  which  exceeded  SI. 00  per  ton 
except  in  23418  where  the  estimated  shortage  was  $1.14. 


GROUND    BONE  43 

TANKAGE. 

Taiikage  is  prepared  from  animal  refuse  secured  from  slaughter 
houses  and  meat  markets  and  may  contain  considerable  and 
varying  amounts  of  bone.  The  distinction  between  meat  tankage 
and  bone  tankage  is  not  sharply  drawn  but,  in  general,  tankage 
with  5  per  cent  or  less  of  nitrogen  and  15  per  cent  or  more  of 
phosphoric  acid  shows  considerable  bone  and  is  often  sold  as  bone 
and  meat  tankage.  As  the  nitrogen  content  increases,  phosphoric 
acid  becomes  less,  and  in  tankage  containing  over  5  per  cent  of 
nitrogen  there  is  generally  less  than  15  per  cent  of  phosphoric 
acid,  indicating  a  preponderance  of  meat.  According  to  defini- 
tions established  for  tankage  to  be  used  for  feeding  purposes, 
phosphoric  acid  in  excess  of  10  per  cent  is  regarded  as  bone  and 
meat  tankage. 

Fineness  is  an  important  factor  in  determining  the  utilization 
of  tankage  by  crops,  particularly  in  those  products  containing  the 
higher  amounts  of  bone. 

Eighteen  samples  have  been  analyzed  and  analyses  are  given  in 
Table  XII. 

Sample  171  was  drawn  to  check  the  results  obtained  on  23142. 
Sample  23021  was  sold  direct  to  the  user  and  was  reinforced  with 
bone  phosphate  at  the  direction  of  the  purchaser. 

On  the  basis  of  the  classification  suggested  above  there  are  six 
samples  in  which  the  nitrogen  is  less  than  5  per  cent  and  the  phos- 
phoric acid  more  than  15  per  cent;  in  the  remaining  twelve  the 
reverse  is  true,  i.  e.,  nitrogen  is  more  than  5  per  cent  and  phosphoric 
acid  is  less  than  15  per  cent.  In  the  first  group  the  average  nitrogen 
is  4.14  per  cent  and  the  average  phosphoric  acid  is  19.86  per  cent, 
which  approaches  the  composition  of  bone.  The  average  of 
quoted  prices  is  $34.79. 

In  the  second  group  the  averages  for  nitrogen  and  phosphoric 
acid  are  6.62  and  10.35  per  cent  respectively,  and  the  average 
price  quoted  is  $46.99. 

GROUND  BONE. 

Twenty-six  samples  were  analyzed  and  results  are  given  in 
Table  XIII. 

'The  guaranties  for  nitrogen  and  phosphoric  acid  were  met  in 
almost  all  cases,  generally  with  a  considerable  overage.  Two 
samples  which  were  deficient  in  phosphoric  acid,  23129  and  43, 
contained  excesses  of  nitrogen  which  more  than  balanced  the 
deficiencies. 

In  fifteen  samples  50  per  cent  or  more  of  the  material  was  finer 
than  l/50th  of  an  inch,  and  in  five,  60  per  cent  or  more  was  of 
that  degree  of  fineness. 

Prices  quoted  ranged  from  $36.50  to  $66.00,  the  average  being 
$49.72.  The  averages  for  nitrogen  and  phosphoric  acid  were  3.42 
and  24.16  per  cent  respectively.  Allowing  27  cents  per  pound  for 
nitrogen,  phosphoric  acid  from  this  source  has  cost  6.5  cents  per  pound.

MIXED    FERTILIZERS  53 

MIXTURES     CONTAINING     AMMONIA,     PHOSPHORIC     ACID 

AND  POTASH. 

In  Table  XIV  are  given  analyses  of  two  hundred  and  ninety- 
nine  samples  of  complete  fertilizers.  Two  hundred  and  eighty- 
two  were  drawn  officially  by  the  Station  agent  and  seventeen  were 
submitted  by  purchasers. 

In  the  column  headed  "grade"  appear  the  figures  which  repre- 
sent the  guaranteed  amounts  of  ammonia,  available  phosphoric 
acid  and  potash  in  the  order  named;  thus,  4-8-4  means  that  the 
brand  is  guaranteed  to  contain  4  per  cent  of  ammonia,  8  per  cent 
of  available  phosphoric  acid  and  4  per  cent  of  potash.  In  the 
analyses  on  the  right  hand  pages  of  the  table  the  corresponding 
percentages  of  these  constituents  as  found  appear  in  bold  face 
type. 

Concerning  Guaranties. 

Of  the  two  hundred  and  eighty-two  official  samples,  one  hun- 
dred and  twenty,  or  about  40  per  cent,  failed  to  completely  satisfy 
their  guaranties,  deficiencies  of  0.12  per  cent  in  ammonia, '0.2 
per  cent  in  available  phosphoric  acid  and  0.15  per  cent  in  potash 
being  disregarded.-  Each  sample  requires  three  major  determina- 
tions in  order  to  check  the  guaranty,  hence  eight  hundred  and  forty- 
six  determinations  have  been  required  for  the  official  samples 
in  this  group.  Since  some  samples  have  been  deficient  in  more 
than  one  item,  the  total  number  of  deficiencies  found  was  one 
hundred  and  forty-nine;  in  other  words,  about  82.4  per  cent  of 
the  individual  items  of  plant  food  guaranteed  have  been  substan- 
tially correct  or  in  excess  of  guaranties. 

Taking  the  total  number  of  samples  of  each  manufacturer  who 
registered  three  or  more  brands,  and  calculating  from  the  analyses 
the  average  shortage  or  overrun  in  elements  of  plant  food  guar- 
anteed, we  deduce  the  following  summary: 

Of  26  manufacturers, — 

16  equaled  or  exceeded  guaranties  in  the  three  elements. 
9  equaled  or  exceeded  guaranties  in  two  elements  and  were 

short  in  one. 
1  equaled  or  exceeded  the  guaranty  in  one  element  and  was 
short  in  two. 

Nine  of  the  shortages  were  in  ammonia  and  there  was  one  each 
in  available  phosphoric  acid  and  potash.  The  ammonia  deficien- 
cies ranged  from  0.10  to  0.53  per  cent;  seven  were  less  than  0.25 
per  cent.  The  deficiencies  in  available  phosphoric  acid  and 
potash  were  0.15  and  0.19  per  cent  respectively. 


54  CONNECTICUT    EXPERIMENT    STATION  BULLETIN   261. 

Analyses  Requiring  Special  Comment. 

Special  coniment  or  explanation  is  due  in  connection  with  the 
following  analyses : 

185.  Aben  Hardware  Co.  This  sample  represents  a  part  of  a 
cargo  of  fertilizer  salvaged  from  a  wrecked  vessel.  The  goods  were 
found  to  be  under  guaranty  but  they  were  sold  for  a  price  at  which 
the  purchaser  suffered  no  loss. 

158.  Am.  Agr.  Chem.  Co.,  3-8-4.  The  manufacturer  obtained 
3.74  per  cent  of  potash  on  a  duplicate  portion  of  our  sample. 
Our  report  for  potash  was  3.71  per  cent.  On  159,  5-8-7  of  the  same 
manufacturer,  their  result  for  potash  was  6.71  per  cent;  our 
report  was  6.50  per  cent. 

Five  of  the  Armour  brands  have  shown  considerable  deficiencies. 
Second  samples  were  analyzed  in  nearly  all  cases. 

23398.  Atlantic  Tobacco  Manure  5-8-6.  This  was  found  below 
guaranty  in  ammonia;  a  second  sample,  172,  from  another  source, 
was  also  low.  The  results  for  the  two  samples  were  4.44  and  4.77 
respectively. 

23125.  Berkshire  Complete  Tobacco  5-3-5.  This  showed 
4.83  per  cent  ammonia  but  a  second  sample,  5,  from  another  source 
showed  5.22  per  cent.  The  average  analysis  for  the  two  samples 
is  5.03-3.89-5.78,  which  meets  the  guaranty. 

23301.  This  sample  was  drawn  as  Chittenden's  Top  Dresser 
6-8-4,  but  analysis  showed  it  to  be  a  4-8-4  brand.  Investigation 
was  made  but  it  could  not  be  determined  beyond  doubt  whether 
Potato  Manure  was  packed  in  bags  marked  "Top  Dresser"  or 
whether  an  error  in  sampling  had  occurred.  A  second  sample 
could  not  be  obtained  from  this  or  any  other  purchaser  and  the 
sample  is,  therefore,  accepted  as  a  4-8-4  brand. 

23392.  Clark's  Special  Mixture,  4-8-4,  was  reported  low  in 
ammonia  and  potash,  but  a  second  sample,  299,  was  found  to  meet 
the  guaranty.  The  average  of  the  two  analyses  is  3.78-8.69-3.99 
which  satisfies  the  guaranty,  except  in  ammonia,  and  shows  no 
significant  deficiency  in  money  value. 

23038.  Frisbie's  Special  3-8-4,  was  reported  low  in  total 
phosphoric  acid;  a  second  sample,  23305,  was  below  guaranty  in 
total  phosphoric  acid  and  in  potash.  Available  phosphoric  acid 
was  satisfactory  in  both  cases.  The  average  for  the  two  samples 
is  2.94-8.17-3.82. 

22992.  Frisbie's  4-8-4  was  reported  low  in  ammonia  and 
potash;  the  second  sample,  23274,  was  likewise  deficient.  The 
average  for  the  two  analyses  is  3.76-8.51-3.73. 

22990.  Frisbie's  5-8-7  was  low  in  ammonia,  and  the  second 
sample,  23273,  was  deficient  in  ammonia  and  potash.  The  average 
of  the  two  analyses  was  4.70-8.85-6.79. 


MIXED    FERTILIZERS  55 

22984.  Frisbie's  7-5-4  was  reported  low  in  ammonia,  and  the 
second  sample,  162,  was  also  below  guaranty  in  this  respect.  The 
average  of  both  analyses  is  6.52-5.65-4.10. 

23037.  Lowell  5-8-7,  and  23041,  Lowell  4-8-4.  These  two 
samples  were  found  to  be  below  guaranty  in  ammonia.  Portions  of 
our  samples  were  submitted  to  the  manufacturer  and  the  check 
results  were  in  close  agreement  with  our  figures. 

23243.  Lowell  Tobacco  5-4-5  was  found  low  in  ammonia  but 
the  second  sample,  8,  was  not  deficient.  The  average  of  two  anal- 
yses is  4.87-5.05-5.26. 

23154.  Naco  Brand  2-8-2.  This  brand  is  called  2-8-2  but  its 
actual  guaranty  is  2.8-1L3-2.8,  the  idea  being  that  the  purchaser 
is  to  understand  that  a  pound  of  this  brand  will  contain  the 
same  amount  of  plant  food  as  one  and  2/5  pounds  of  a  2-8-2 
grade.  Several  other  brands  of  the  Nitrate  Agencies  goods  are 
listed  on  this  "equivalent"  plan.  Registrations,  however,  should 
declare  the  percentage  amounts  of  elements  in  the  goods  as  sold. 
To  have  the  brand  indicate  one  grade  and  the  analysis  another 
leads  only  to  confusion. 

23060.  Royster's  Top  Dresser  7-6-5  was  found  to  be  low  in 
ammonia.  Analysis  of  a  duplicate  portion  of  our  sample  by  the 
manufacturer  confirmed  our  result. 

23189.  Virginia-Carolina  4-8-6;  23193,  3-9-5;  and  92,  8-6-6. 
Duplicate  portions  of  our  samples  were  sent  to  the  manufacturer 
and  their  results  were  in  substantial  accord  with  ours  in  all  cases. 

The  Rogers  and  Hubbard  Co.  advise  us  that  very  discordant 
results  for  available  phosphoric  acid  have  been  reported  to  them 
by  control  and  by  commercial  laboratories  on  their  bone-base 
goods.  In  this  connection  it  should  be  noted  that  so-called 
"available"  phosphoric  acid  is  largely  influenced  by  the  method 
of  determining  citrate-insoluble  phosphoric  acid,  which  method 
was  devised  for  use  upon  acid  phosphate  and  which  does  not 
accurately  evaluate  phosphoric  acid  from  other  sources  such  as 
bone,  tankage,  etc. 

Deficiencies  in  Money  Value. 

In  eighteen  brands  deficiencies  have  amounted  to  more  than  a 
dollar  per  ton,  the  values  being  arrived  at  by  balancing  overruns 
against  shortages  and  reckoning  ammonia  at  21  cents  per  pound 
and  available  phosphoric  acid  and  potash  each  at  4  cents  per 
pound.  Where  more  than  one  sample  of  a  given  brand  has  been 
analyzed  the  commercial  shortage  has  been  estimated  on  the  basis 
of  the  average  of  the  analyses  made.  The  brands  thus  found 
deficient  are  listed  in  Table  XV.

The  products  of  a  given  mantifacturer  are  more  adequately 
judged  on  the  record  over  a  period  of  years  than  on  the  results  of 
a  single  inspection.  If  the  data  given  in  Table  XV  is  combined 
with  similar  data  for  the  preceding  three  years  and  compared  with 
the  total  number  of  samples  of  each  manufacturer's  goods  analyzed 
in  this  four-year  period,  we  find  that  of  approximately  one  thou- 
sand samples,  about  one  hundred  have  shown  deficiencies  in  money 
value  of  more  than  $1.00  per  ton.  In  other  words,  purchasers 
have  obtained  commercial  values  substantially  equal  to  guar- 
anties, or  in  excess  of  the  same,  in  about  90  per  cent  of  the 
purchases  represented.  This  is  shown  in  more  detail  in  the  ac- 
companying tabulation,  Table  XVI.  A  manufacturer's  name  does 
not  appear  unless  ten  or  more  official  samples  have  been  analyzed 
in  the  four-year  period,  and  the  figures  refer  to  individual  samples 
and  not  to  averages.

About  70  per  cent  of  the  two  hiindred  and  eighty-two  samples 
examined  have  carried  guaranties  of  ammonia  of  4  per  cent  or 
over.  A  tabulation  for  the  last  four  years  shows  the  distribution

The  "New  England  Standard  Nine." 

The  number  of  grades  represented  by  the  two  hundred  and 
eighty-two  samples  of  complete  fertilizers  and  two  of  the  group 
containing  potash  and  phosphoric  acid  only  is  seventy-four.  The 
number  of  samples  falling  in  the  "Standard  Nine"  grades  is  ninety- 
six;  but,  if  several  grades  closely  corresponding  to  these  are  in- 
cluded, the  number  is  increased  to  one  hundred  and  twenty- 
seven.  What  proportion  of  the  total  tonnage  in  this  State  is 
represented  by  the  "Standard  Nine"  cannot  be  stated  at  this 
time.  Less  than  one-half  of  the  samples  examined  have  fallen 
in  the  selected  grades  or  those  closely  corresponding  thereto. 

In  the  following  siunmary  the  "vStandard  Nine"  grades  are  in- 
dicated in  full  face  type.

Quality  of  the  Nitrogen  in  Mixed  Fertilizers. 

The  nitrogen  derived  from  nitrates  and  from  ammonium  salts 
is  soluble  in  water  and  its  utilization  by  plants  is  relatively  rapid 
and  complete.  A  portion  of  the  organic  nitrogen  may  also  be 
soluble  in  water  and  this  is  presumably  more  readily  utilized  by 
plants  than  that  portion  which  is  insoluble.  For  many  years  it 
has  been  the  practice  of  agricultural  chemists  to  evaluate  approx- 
imately the  insoluble  organic  nitrogen  of  fertilizers.  Two  methods 
are  employed  for  this  purpose,  both  of  which  depend  upon  the 
action  of  dilute  solutions  of  permanganate  of  potash  upon  the 
nitrogenous  material  under  examination,  the  one  an  alkaline  solu- 
tion, the  other  a  neutral  solution.  The  results  do  not  measure 
the  availability  of  the  insoluble  nitrogen  in  the  generally  accepted 
sense  of  that  term,  but  they  parallel  vegetation  tests  to  the  extent 
that  low  activity  values  indicate  forms  of  nitrogen  which  show 
poor  crop-producing  power. 


MIXED    FERTILIZERS  59 

In  judging  the  quality  of  the  insoluble  nitrogen  it  is  our  practice 
to  apply  the  alkaline  permanganate  method  in  all  cases  where  the 
amount  of  the  insoluble  exceeds  3/10  of  one  per  cent.  If  less 
than  50  per  cent  activity  is  shown,  the  neutral  method  is  used, 
check  determinations  being  made  in  both  cases.  Activity  values 
of  less  than  50  per  cent  by  the  alkaline  method  and  less  than  80 
per  cent  by  the  neutral  method  are  interpreted  as  indicating  in- 
ferior forms  of  nitrogenous  material. 

Four  samples  this  year  showed  results  for  active  insoluble  nitro- 
gen less  than  the  limits  just  quoted.  In  two  of  them  the  actual 
amounts  of  insoluble  nitrogen  were  small  (0.3  to  0.4),  constituting 
only  about  1/10  and  1/4  respectively  of  the  total  nitrogen,  and 
judgment  was  suspended.  In  Super- Alphano  (127)  and  Woodruff's 
Home  Mixture  (23188) ,  the  insoluble  nitrogen  constituted  3/5  and 
2/5  respectively  of  the  total,  and  the  activity  figures  were  44.4 
and  41.8  per  cent  respectively  by  the  alkaline  method  and  55  and 
74.2  per  cent  respectively  by  the  neutral  method.

VII.     MISCELLANEOUS    FERTILIZERS,    AMENDMENTS 

AND  WASTE  PRODUCTS. 

WOOD  ASHES. 

Twenty  samples  have  been  examined.  No.  22959  was  wet  and 
low  in  potash.  No.  23302  was  also  low  grade.  The  other  samples 
submitted  contained  from  4.80  to  7.83  per  cent  of  potash  and 
were  of  good  quality.  Wood  ashes  contain  from  1  to  2.5  per 
cent  of  phosphoric  acid  and  30  per  cent  or  more  of  lime,  but  they 
are  an  expensive  source  of  potash.  The  prevailing  price  quoted 
is  $5.00  per  unit,  which  is  about  five  times  the  cost  of  other 
equally  available  forms  of  potash. 

Analyses  are  given  in  Table  XVIII. 

SHEEP  MANURE,  ETC. 

Fourteen  samples  of  this  class  of  materials  have  been  analyzed, 
ten  of  which  were  sampled  by  the  Station  agent.  Analyses  are 
given  in  Table  XIX. 

Ton  prices  have  ranged  from  $30.00  to  $50.00,  the  average 
being  about  $45  00.

LIME. 

The  application  of  lime  for  purposes  of  soil  improvement  has 
been  practiced  since  very  remote  times.  Marl  and  ash  were  used 
for  this  by  the  ancient  Greeks  and  Romans  and  in  early  English 
history  the  practice  of  spreading  chalk  on  the  land  is  recorded. 
The  early  colonists  in  America  brought  the  practice  with  them, 
and  marl,  ashes,  and  gypsum  or  land  plaster  are  conspicuous  in 
the  records  of  colonial  agriculture.  With  the  advent  of  artificial 
fertilizers  the  use  of  liming  materials  was  largely  suspended  but 
modern  agricultural  practice  has  restored  lime  to  wider  recog- 
nition than  ever  before. 

In  the  earlier  sense  of  the  term  "lime",  a  miscellaneous  group 
of  calcium-containing  materials  were  included  such  as  marls, 
chalk,  oyster  and  clam  shells,  limestone,  marble,  and  the  ashes 
of  wood  and  other  organic  substances  in  which  calcitmi  is  com- 
bined wholly  or  in  part  as  carbonate ;  gypsum  or  land  plaster  which 
is  calcium  sulphate;  and  phosphate  of  lime  which  is  derived  from 
phosphatic  rocks  and  from  bone.  The  current  usage  of  the  term, 
however,  is  more  restricted  and  applies  chiefly  to  calcitic  and 
dolomitic  limestones,  oyster  shell  lime,  calcareous  marls  and  the 
several  forms  of  lime  derived  from  them. 

The  practical  use  of  lime  in  New  England  may  be  discussed  very 
briefly  as  follows: 

1.  The  chief  function  of  lime  is  to  make  the  soil  less  "acid". 
The  exact  nature  of  this  "acidity"  is  a  matter  on  which  scien- 
tists are  not  entirely  agreed,  but  all  agree  that  lime  will  change 
the  reaction. 

2.  The  soils  of  Connecticut  are  usually  acid,  due  to  lime 
deficiency  of  the  rock  from  which  they  are  derived,  the  relatively 
high  leachiness  of  our  soils,  and  the  long  period  of  time  which 


MISCELLANEOUS    FERTILIZERS,    ETC.  93 

most  of  the  tillable  area  has  been  under  cultivation.  Also,  due  to 
the  variable  factors  of  original  soil  material,  leachiness  and  past 
agricultural  practice,  our  soils  vary  widely  in  the  degree  of 
acidity. 

3.  We  are  not  so  much  concerned  with  soil  acidity  as  such, 
as  with  the  success  of  a  large  number  of  crops  such  as  clover, 
alfalfa,  timothy,  redtop,  tobacco,  potatoes,  tomatoes,  lettuce, 
beets,  carrots,  spinach  and  many  others.  It  has  also  been 
shown,  particularly  by  the  Rhode  Island  Station,  that  crops 
vary  greatly  in  their  sensitiveness  to  acidity  and  in  their  response 
to  applications  of  lime.  For  instance,  red  top,  strawberries 
and  watermelons  do  very  well  under  acid  conditions  while  others, 
like  beets,  onions  and  alfalfa,  require  a  condition  much  less  acid. 
Certain  diseases,  like  potato  scab  and  tobacco  root-rot,  are  con- 
trolled by  keeping  the  soil  moderately  acid. 

4.  A  knowledge  of  the  intensity  of  soil  acidity  is  manifestly 
of  great  importance  as  a  guide  to  farm  practice  in  regard  to 
any  given  crop  to  be  grown.  The  "litmus  paper"  test  was 
formerly  used  in  this  connection,  but  it  is  not  sufficiently  sen- 
sitive to  show  the  finer  distinctions  in  soil  reaction  that  modern 
research  has  shown  to  be  necessary,  and  there  are  much  better 
methods,  which,  while  far  more  perfect,  do  give  a  fairly  accurate 
estimate  of  the  degree  and  intensity  of  the  acidity. 

5.  Our  liming  practice  should  therefore  be  based  on  the 
following  information : 

a-    What  crops  are  to  be  grown? 
b-    What  amounts  of  stable  manure  are  used? 
c-    What  kinds  and  amounts  of  fertilizer  are  used  ? 
d-    When,  in  what  form  and  what  amounts  has  lime  been 
used? 

e-    What  is  the  reaction  of  the  soil? 

This  last  can  be  learned  by  sending  representative  samples 

from  various  fields  to  the  Experiment  Station.     Such  samples 

should  be  accompanied  by  the  information  indicated  in  a,  b,  c 

and  d  above,  if  advice  is  desired  relative  to  the  use  of  lime. 

The  inference  should  not  be  drawn  that  we  now  have  accurate 

information  on  all  the  problems  concerned  with  "acidity,"  but 

progress  is  being  made  and  on  certain  crops  there  is  quite  accurate 

information. 

The  relation  between  actual  lime  (calcium  oxide,  CaO),  and  the 
several  natural  and  manufactured  lime  products  is  illustrated  as 
follows:  If  100  lbs.  of  pure  crushed  limestone  are  burned  in  a 
kiln  at  suitable  temperature  (650-900  °C.  or  1200-1650  °F.),  56 
pounds  of  actual  lime  (calcium  oxide,  CaO),  are  obtained,  the 
remaining  44  pounds  being  lost  in  the  form  of  carbon  dioxide  gas 
(CO2).  This  actual  lime  is  known  also  by  other  names  such  as 
"stone  lime"  or  "quicklime".      Actual  lime  or  quicklime  is  very 


94  CONNECTICUT    EXPERIMENT    STATION  BULLETIN   261. 

irritating  to  handle  and  in  practice  slaked  lime  is  more  often  used. 
This  is  obtained  by  treating  quicklime  with  water,  with  which  it 
combines  vigorously  with  the  production  of  considerable  heat. 
There  is  enough  moisture  in  the  air  to  accomplish  the  slaking 
process,  but  a  longer  time  is  required.  The  56  lbs.  of  actual  lime 
obtained  from  the  original  100  lbs.  of  limestone  will  obviously 
increase  in  weight  as  it  combines  with  water  and  will  weigh  74 
lbs.  when  completely  slaked.  This  slaked  lime  is  otherwise  known 
as  hydrated  lime,  calciiim  hydrate  or  calcium  hydroxide.  When 
quicklime  is  allowed  to  air-slake,  however,  it  absorbs  carbonic 
acid  as  well  as  moisture  from  the  air  so  that  the  product  is  a  mix- 
ture containing  some  quicklime,  hydrated  lime  and  carbonate  of 
lime,  or,  in  other  terms,  calcium  oxide,  calcium  hydrate  and 
calcium  carbonate. 

The  changes  described  take  place  also  in  the  case  of  limestones 
which  contain  magnesium  (dolomitic  limestones),  the  product  of 
burning  being  in  such  cases  the  mixed  oxides  of  lime  and  magnesia. 

Commercial  liming  materials  are  judged  on  the  basis  of  actual 
lime  and  magnesia  (oxides  of  calcium  and  magnesium) ,  which  they 
contain,  and  upon  their  degree  of  fineness.  The  various  products 
are  quite  variable  in  composition  but  in  general  they  will  contain 
mixed  oxides  about  as  follows :

Lime  ashes 50-60 

The  effectiveness  of  lime  in  the  soil  will  depend  directly  upon 
its  degree  of  fineness.  Neither  the  carbonates  nor  hydrated  limes 
are  readily  soluble  in  soil  water  and  the  rate  at  which  they  will 
be  dissolved  will  depend  upon  the  size  of  the  particles.  The  smaller 
the  grains  the  greater  the  relative  amount  of  surface  exposed  to 
the  action  of  the  solvent. 

Fineness  of  Lime. 

Since  there  is  a  direct  relationship  between  the  fineness  of  lime 
products  and  their  rate  of  availability  in  the  soil,  it  might  appear 
that  the  greatest  degree  of  fineness  is  desirable.  Yet  because  of 
the  cost  of  grinding  the  lime  to  a  very  fine  condition  and  the  rapid- 
ity with  which  such  material  disappears  in  the  soil,  a  medium 
ground  lime  seems  to  be  the  more  desirable  commercial  product. 
A  reliable  authority  assumes  that  pulverized  limestone,  all  of 
which  will  pass  a  10  mesh  sieve,  70%  of  which  will  pass  a  50  mesh 


MISCELLANEOUS    FERTILIZERS,    ETC.  95 

sieve,  and  50%  of  which  will  pass  a  100  mesh  sieve,  should  give 
excellent  results  and  yet  be  cheap  enough  to  make  its  use  worth 
while.  In  Ohio  the  standard  required  by  law  for  agricultural 
ground  limestone  is  that  95%  of  the  material  shall  pass  a  10  mesh 
screen,  50%  shall  pass  a  50  mesh  screen,  and  30%  shall  pass  a 
100  mesh  screen. 

If  immediate  effects  are  desired  in  the  use  of  moderate  quan- 
tities of  lime  for  a  special  crop  of  high  money  value,  extreme  fine- 
ness may  be  desirable,  regardless-  of  the  greatly  increased  cost. 
This  is  usually  obtained  in  hydrated  limes. 

In  table  XX  are  given  analyses  of  46  samples  of  lime.  Some  of 
these  were  collected  and  examined  two  years  ago  but  the  results 
have  not  been  published. 

Comments  on  Analyses. 

22349.  This  was  a  sample  of  Hmestone  dust  which  accumulated 
in  the  manufacture  of  poultry  grit  and  was  not  offered  for  sale  as 
an  agricultural  lime. 

23030,  23031,  23254.  The  first  two  samples  were  submitted  by 
purchasers.  The  manufacturer  advised  that  the  analysis  of 
23030  was  quite  unlike  the  composition  of  their  product  as  shown 
by  frequent  check  analyses  of  their  own.  Accordingly  an  official 
sample,  23254,  was  drav/n  which  was  supposed  to  be  the  same 
material  as  23030  but  was  sampled  from  different  stock.  This 
showed  a  composition  substantially  in  accord  with  the  manu- 
facturer's claim  and  in  agreement  also  with  purchaser's  sample 
23031.  Evidently  23030  had  become  mixed  with  some  material 
containing  a  relatively  large  amount  of  insoluble  matter. 

The  cost  of  lime,  so  far  as  ton  prices  have  been  quoted  to  us, 
show  considerable  variation.  Thus,  four  quotations  for  limestone 
have  varied  from  $6.75  to  $10.00  per  ton.  For  hydrated  lime, 
containing  from  62  to  77  per  cent  of  effective  oxides,  prices  have 
ranged  from  .$9.50  to  $15.00.

MISCELLANEOUS.    ~ 

23430.     Potash-Marl.     Potash-Marl,   Inc.,    New  York.     Sam- 
pled by  the  Station  agent  from  stock  of  F.  H.  Leggett  &  Co., 
Stamford.     Only  phosphoric  acid  is  guaranteed. 
Analysis : 

Available  phosphoric  acid  found  0.42  per  cent,  guaranteed  0.47  per  cent, 
total  1.05  per  cent,  guaranteed  1.30  per  cent. 

This  material  may  contain  6  per  cent  or  more  of  potash  not, 
however,  in  water  soluble  forms.  The  phosphoric  acid  and  total 
potash  in  this  fertilizer  are  probably  overvalued  at  $5.00  per  ton 
but  the  price  quoted  is  $40.00. 

174.  Carbit.  The  Hyper-Humus  Co.,  Newton,  N.  J.  This 
material  was  sampled  from  the  stock  of  Olds  and  Whipple,  Inc., 
Hartford.  The  chief  value  claimed  for  it  by  the  manufacturers 
is  to  be  found  in  the  beneficial  bacteria  with  which  it  is  inoculated. 
The  Station  cannot  judge  its  worth  from  that  standpoint.  It  is 
recommended  for  tobacco  and  its  usefulness  can  only  be  deter- 
mined by  experiment. 

23235  and  23370.  Hair  Tankage.  Berkshire  FertiHzer  Co., 
Bridgeport.  Sampled  by  Station  agent  at  the  factory.  The  two 
samples  contained  2.74  and  3."34  per  cent  of  ammonia  respectively. 
It  was  guaranteed  to  contain  3  per  cent  ammonia. 

22966.  Base  Goods.  The  Rogers  and  Hubbard  Co.,  Portland. 
This  material  was  examined  for  quality  of  its  nitrogen  as  follows : 

Nitrogen  in  nitrates  0.26  per  cent,  in  ammonia  0.68  per  cent,  water- 
soluble  organic  2.02  per  cent,  water-insoluble  organic  2.18  per  cent,  total 
5.14  per  cent. 

The  activity  of  the  insoluble  organic  nitrogen  was  66.2  per  cent 
by  the  alkaline  method  and  89.6  per  cent  by  the  neutral  method. 

22498.  Burnt  Bone.  This  was  a  waste  product  sent  by  R.  E. 
Gerth  of  West  Hartford.  Most  of  the  nitrogen  had  been  destroyed 
but  the  phosphoric  acid  content  was  38.92  per  cent. 

22967  and  22699.  Coal.  The  first  was  a  sample  of  Station  coal 
and  the  second  was  submitted  by  C.  Q.  Eldredge  of  Mystic.  They 
contained  8.56  and  21.77  per  cent  of  ash  respectively. 

Eight  other  samples  of  unclassified  materials  including  soils 
require  no  particular  comment. 

CHECK  COTTONSEED  MEAL  AND  CHECK  FERTILIZERS. 

The  laboratory  has  continued  its  co-operation  in  the  program 
of  the  American  Oil  Chemists'  Society  in  testing  weekly  samples 
of  cottonseed  meal,  and  of  the  Royster  Guano  Co.  in  analyzing 
monthly  samples  of  various  fertilizers.  Thirty  samples  of  meal 
and  twelve  of  fertilizers  have  been  reported.
